METHOD AND APPARATUS FOR LAMINATING GLASS SHEETS

摘要

The invention relates to a method and apparatus for laminating glass articles without using an autoclave. The sandwich structure to be laminated is preheated then is placed in a controllable vacuum and subjected to electromagnetic radiation with specified frequencies and power. The preheating and final heating are provided by convectional heat source. Pressure that is applied continuously during the radiating, heating and cooling steps is also specified for achieving an appropriate bond. An apparatus appropriate for realizing the invented process is also provided. The apparatus includes a loading table, three furnaces, and a cooling chamber which are adjusted to and adjoined to each other. These parts provide the necessary conditions for high-quality laminating simple and multi-sandwich structures with high production rate and efficiency. The apparatus is inexpensive and fits into the space of two glass article lengths.
